RANGE-BOILER.

SPECIFICATION forming part of Letters Patent No. 352,375, dated November 9, 1886 Application filed December 5, 1885. Serial No. 184,769. (No model.)

To aZZ whom it may concern.-

' Be it known that I, JoHN TUCKER, of the city, county, and State of New York, haveinvented certain new and useful Improvements in Range-Boilers, of which the following is a specification.

The range-boilers in general usein dwellings keep the kitchen and lower floors well supplied with hot water, but are not capable of suppl ying a suficient quantity of hot water to the upper floors,to the great annoyance of the occupants of the same. A second boiler is therefore used inconnection with the laundry-range, which boiler is used for supplying the upper stories.

This, however, requires that a fire be kept up in the laundry-range, which is inconvenient and expensive.

The object of this invention is to furnish animproved rangeboiler that is adapted to supply a sufficient quantity of hot water for kitchen and laundry use as well as for the upper floors of the building; and the invention consists of two or more boilers connected by pipes with an intermediate heater, said heater being composed of an outer shell and an interior tubular body having closed heads. One of the boilers is connected to the outer shell and the space around the tubular body, while the outer boiler or boilers are connected to the interior tubular body. The water-back of the range is connected by pipes to the outer shell of the heater, so as toheat directly the water of one boiler, while the water of the other boiler is heated indirectly by the heat transmitted to the interior tubular body of the heater by the hot water of the first boiler.

In the accompanying drawings, Figure 1 represents a side elevation of my improved rangeboiler. Fig. 2 is a detail vertical central section of the heater, drawn on a larger scale. Fig. 3 is a horizontal section on line a: m, Fig. 1; and Fig. 4 is a side view of three boilers connected to one heater, which latter is shown in vertical section. Y

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A and A are two range-boilers of the usual size, shape, and material, which are supported -on stands of the usual construction. lntermediately between the range-boilers A A is supported a heater, B, Which is made of cylindrical shape and 00111- posed of an outer shell, b, and an interior tubular body, d, having closed heads (2.

The heater B is connected by two sets of pi )es a a a a with the boilers A A, thepipes a a connecting the boiler A, respectively,with

Water-back O of the range, which water-back heats up the water supplied by the boiler A and keeps up the circulation of the water through said boiler and the space surrounding the interior tubular body, d, of the heater. The heat of the water of the range-boiler A heats up the water in the interior tubular body, d, and the water in the range-boiler A to nearly the same degree of heat of the water in the boiler A. The boiler A is connected to the upper floors of the building and supplies the water required in the bath-room and basins of the sleeping rooms, while the hot water in the boiler A is used for kitchen and other purposes. The water-back D of the laundry-range is also connected by pipesff to one of the boilers A A, so that the heat of the laundry-range can be utilized when the same is used for heating up the range-boilerA or A. By thus coupling two boilers, A and A, by means of a heater, B, that heats them both, alarge quantity of hot Water is obtained and a full supply kept on hand for various purposes.

It a still larger quantity of water should be required, three or four boilers, A A A, 850., may be put up and connected by pipes with the interior tubular body, b, of the heater B,which body is then divided into sections, each additional boiler having its own section of tubes forheating the water in the same, as shown in Fig. 4. lt is obvious that in this case the heater has to be made of a correspondingly larger size, so that the surface area of its heatingpipes is proportionately increased.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination of two or more rangeboilers, a heater composed of an exterior shell and an interior body, pipes connecting the range-boilers, respectively, with the shell and the interior'body of the heater, and a waterback connected by pipes to the heater, sub- In testimony that I claim the foregoing as stantially as set forth. my invention I have'signed my name in pres- 2.
